...MAJOR WINTER STORM TO CONTINUE, ESPECIALLY ACROSS PORTIONS OF  
THE NORTH CAROLINA AND VIRGINIA, EXPECT NEAR-IMPOSSIBLE TRAVEL  
CONDITIONS AND NUMEROUS POWER OUTAGES...  
 
A STRONG STORM SYSTEM OFF THE SOUTHEAST U.S. COAST WILL RESULT IN  
A HIGH IMPACT WINTER STORM FROM EXTREME NORTHEAST GEORGIA AND  
NORTHWEST SOUTH CAROLINA TO CENTRAL/SOUTHERN VIRGINIA. WINTER  
STORM WARNINGS ARE IN EFFECT FROM NORTHEAST GEORGIA TO CENTRAL  
VIRGINIA. SUBSTANTIAL SNOWFALL ACCUMULATIONS ARE LIKELY ACROSS  
THE SOUTHERN APPALACHIANS AND THE ADJACENT PIEDMONT OF NORTH  
CAROLINA AND SOUTH-CENTRAL VIRGINIA, WITH SOME ACCUMULATIONS IN  
EXCESS OF A FOOT POSSIBLE THROUGH SUNDAY NIGHT WHERE THE BEST  
LOW-MID LEVEL FORCING BECOMES ESTABLISHED. TRAVEL WILL BE  
SEVERELY AFFECTED ACROSS MUCH OF THESE AREAS, AND SOME POWER  
OUTAGES ARE LIKELY. MIXED PRECIPITATION AND WET SNOW TO THE SOUTH  
AND EAST OF THE HEAVIEST SNOWFALL AXIS ACROSS THE COASTAL PLAIN OF  
THE CAROLINAS AND SOUTHERN VIRGINIA WILL TEND TO LOWER OVERALL  
ACCUMULATIONS THERE, BUT MAY STILL DISRUPT TRAVEL.  
 
ELSEWHERE, A FRONT MOVING ONSHORE OVER THE NORTHWEST WILL MOVE  
INLAND TO THE NORTHERN PLAINS TO THE GREAT BASIN/SOUTHWEST BY  
TUESDAY. THE SYSTEM WILL PRODUCE HEAVY SHOWERS AND MOUNTAIN SNOW  
ACROSS THE PACIFIC NORTHWEST WITH SNOW MOVING INTO THE NORTHERN  
INTERMOUNTAIN REGION BY MONDAY AFTERNOON AND PARTS OF THE  
NORTHERN/CENTRAL ROCKIES BY TUESDAY.
